HIPPOLYTE PLANOHE AND LEON PLANOHE, ()F SALINS, FRANCE.

ENVELOPE.

SPECIFICATION forming part of Letters Patent No. 225,864, dated March 23, 1880.

Application filed October 4, 1879.

To all whom it may concern:

Be it known that we, HIPPoLYTE PLANOHE and LEON PLANGHE, of Salins, Jura, in the Republic of France, have invented Improvements in Closing Bags of Paper, Linen, &c., of which the following is a specification.

This invention relates to the mode of clos' ing paper bags intended for use in sending samples by post, and for many other uses.

Our invention consists in a novel form of paper blank adapted to be folded to form a paper bag, and in a bag formed from such a blank without the use of any accessory. such as gum, eyelets, ties, &c., in closing the bag.

In order that our invention may be well understood, we have represented on the annexed sheet of drawings, at Figures 1, 2, 3, 4, and 5, several modes of preparing sheets of paper to make sample-bags.

The part or lip A is to be folded and glued to form the bottom in the usual manner. The shape and the size of the bag may be changed without interfering with the mode of closing, and the lower angle can be rounded, as at B, or it may be left square; The upper part only relates to the closing of the paper bag.

In Fig. l the angle 0 may be cut ofi' and a straight out made from D to E.

In Fig. 2 the angle 0 may remain, and it may be folded down, following the line I) F, to give more strength to the tongue. The triangle L may be then taken ofi, and the upper angle on the right side of the paper may be taken off, following the line G H, in order to give to the bag greater lightness without decreasing the solidity of the closing.

Fig. 3 shows a combination of Figs. l and 2.

Fig. 4 shows another form of paper blank.

In Fig. 5 a square is cut from the righthand corner. The closing made with this form of blank does not permit the use of this bag for seeds and similar small objects; but it would be suitable for samples of certain dimensions and for business-papers, as it gives solidity as well as lightness.

Figs. 6, 7, 8, 9, and 10 refer specially to the mode of folding to obtain the proper closing of the paper bag, which we will explain in detail in reference to the blank presented, Fig. 3. In this figure the letters 19 m p s s p a t 'r 19 show the out blank.

Fig. 6 shows the first fold, obtained in folding along the line 42 a: to bring the edge t a into coincidence with the line 12 11 Fig. 7 represents the second fold, obtained by turning down the blank on the line 19 p and securing it by glue or other substance to the first flap.

Fig.8 shows the top right-hand corner of Fig. 7 turned down to form the triangle 1) o y, the point being passed under the part 12 s of the small flap previously turned down.

Fig. 9 represents the triangle 1) o y of Fig. 8 folded in half 011 the line 4; 2, which brings the tongue p m p of Fig. 8 in the positio shown in Fig. 9.

It remains now only to close the bag. This is effected by inserting the point we of the tongue 11 m 12 under the previous folds, as shown by dots at Fig. 10. Thus the paper bag is entirely closed, and the smallest objects cannot escape therefrom.

It is understood that this mode of folding the blank under the folds and the insertion of the tongue insure a complete closing of the bag, which has not been hitherto found practicable.

If desired, the part q (shown by dots in the drawings, Fig. 6) can be strengthened by the pasting thereto a small piece of paper, linen, or other suitable material.

Having now described the nature of our invention of improvements in.cl0sing bags of paper, linen, 850., and explained the manner of carrying the same into eifect, we wish it to be understood that we claiml. A paper blank for forming a paper bag having the triangular notch in one side, the opposite corner or angle removed, and the part or lip A at the lower edge for closing the bottom of the bag, substantially as specified.

2. The paper bag consisting of the blank folded upon the lines '0 m 1) p closed at the bottom by the flap or lip A, folded upon the lines 19 g o z, and having the point m inserted under the folds previously made, substantially as. specified.

In testimony that we consider the withindescribed improvement to be our invention we hereunto subscribe our names.
